so....how big is my existance ?

Even up until this moment where i am chatting happily on msn, i wonder, AT ALL TIMES on how small my existance were. There are alot of times that i were only being called when i'm needed at certain time, which usually seasonal, and not something which is cause they want to see me or whatever. Seriously put, how hard is it to say "Thank You" after asking a favour or help from someone ? i'm not saying that every single thing you should say it or appreciate me like a king of whatsoever, but you know what, these things..it build up...as time pass by and you start to get used to taking things for granted, and then you start forgeting how important some existance were until they dissappear..WAAAiiiitdaaaminute...there are chance, that i weren't even remember even if i were to dissappear..probably..
